YARN-CLEARER FOR wiNoiNo-MAcHiNEs'.

SPECIFICATION forming part of Letters Patent No. 646,023, dated March 27, 1906.

Application filed septemher 9, 1899. Serial No. 729,969. (No model.)

To all whom it may concern.-

Be it known that I, HENRY MERCER GIRD- WOOD, flax-spinner, a subject of the Queen of Great Britain, and a resident of Broughton Flax Mills, Salford, in the county of Lancaster, England, have invented certain new and useful Improvements in or Relating to Spinning, Doubling, Reeling, and Winding Machines for Linen, Cotton, and other Yarn, of whichthe following is a specification.

My invention relates to improvements in spinning, doubling, reeling, and winding Inachines for linen, cotton, and other yarn; and the object of my invention is to make a more perfect yarn clearing or cleaning device, so that the yarn will not be chafed nor broken except when a piecing, lump, or otherimper fection meets the clearer.

The clearers commonly in use are formed, say, of a piece of thin metal with a fine slot or two pieces forming a slot through which the yarn passes, the slot in the clearer being usually placed opposite the bobbin, cop, or fly from which the yarn is being drawn. In this construction the yarn meets both back edges of the metal at a right angle, and the consequence of this is that the slot must be very much wider than the thickness of the yarn to let it pass, and even then it chafes the yarn injuriously and also allows some of the piecings and lumps to pass through, thus lessening the value of the yarn. When the slot is made fine enough j ust to allow the yarn where smooth to pass through and so stop the piecings and lumps, the yarn chafes and is out against the back edges of the slot. According to my invention I construct a clearer which obviates the defects mentioned and allows the two parts of the clearer between sharp edge and is set and secured as near as desired to the first-named piece. I

In the accompanying two sheets of draw ings, Figure 1 shows in cross-section part of a yarn-reeling machine with my improved clearer applied. Fig. 2 is a plan of part of the bobbin-rail, illustrating the arrangement of the improved clearers. Fig. 3 is an elevation, and Fig; 4a plan, of part of the bobbinrail, showing two bobbins and clearers full size.

In the views, a designates the bobbin-rail; b, the bobbins; c, the yarn, and d the swift, on which the yarn is reeled, as usual.

Each clearer consists of two parts-namely, a stud or pin e, secured by a nutf to a rail g, this rail being secured by bolts, screws, or other fastenings to the bobbin rail a. The other part of the clearer consists of the blade or cutter h, riveted or otherwise secured to a bracket 2', which is secured adj ustably by screws 3' to the rail g, the screws passing through slots in the rails.

In order to make the bracket 2' adjustable, the screw-holes of the rail g, to which the bracket 1' is fastened, are slotted, so that the cutters h can be set by gages at the proper distance from the studs e for each number or lea of yarn, the heads of the screws j being, preferably, underneath, so that when the rail 9 is fastenedto the bobbin-rail a the clearer cannot be altered by the operative.

As shown clearly in the drawings, the clearer is placed out of the direct line between the bobbin and the swift and so that the yarn 0 must bear against the rounded surface of the stud or pin 6 and only come in contact with the cutting edge of the blade h when piecings or lumps come along,when they are at once caught and the yarn broken.

To compensate for wear by the drag of the yarn, the rail g can be taken off, the nutsf 9o slackened, and the studs 6 or any of them turned partly around to bring an unworn surface into position for the yarn to travel over, after which the nuts f are again tightened up and the rail 9 is replaced.

Having now particularly described and ascertained the nature of my said invention and gentially to said rounded surface, substaIi-' in what manner the same is to be performed, tially as described. I0 I declare that what I claim, and desire to se- In Witness whereof I have hereunto set my cure by Letters Patent of the United States, hand in presence of two witnesses. is- H. M. GIRDVVOOD.
